Autumn: observe the water before touching the garden
In the transition from summer to autumn, the priority is not to prune or fertilise immediately, but to check how the garden responds to the first rains. A soil that waterlogs in one area and dries out in another reveals differences in texture, compaction or slope that will condition any later decision. In Sotogrande and Estepona it is common to find gardens with drip irrigation still programmed as in August; adjusting that schedule to actual moisture avoids excess and fungal problems.
It is worth distinguishing between a wet autumn and a dry one: if the rains arrive early, many Mediterranean plants begin to put out new roots and leaves, and hard pruning at that moment can trigger growth that the cold will later check. If the autumn is dry, supplementary watering remains necessary, especially for young or recently transplanted specimens. Observing the leaves and the feel of the substrate at several points in the garden is more reliable than the calendar.
- Check the irrigation timer after the first rains and adjust it by zones, not across the board.
- Note in a notebook the parts of the garden that waterlog or dry out first; they will guide decisions in the coming seasons.
Autumn: fertilise with judgement and prepare the soil
Fertilising without knowing the soil is one of the most frequent mistakes. In gardens in the area, the soil may be clay, stony or construction fill with little organic matter. Before adding fertiliser, a small analysis or, at least, an observation of texture and drainage avoids adding nutrients the plant will not use. In general, autumn is a good time to incorporate well-decomposed organic matter on the surface and let soil life integrate it, rather than burying it deeply.
Tasks should also be staggered: not every plant needs autumn feeding. Citrus and winter-flowering shrubs may benefit from a moderate input, while hardy aromatic herbs usually respond better to poor, well-drained soil. The decision should be based on the vigour observed during summer and on the species, not on a fixed routine.
- Do not fertilise a plant that has suffered severe water stress until it starts growing again.
- Apply organic matter on the surface and water lightly to integrate it; avoid mixing it with shallow roots.
Winter: structure and rest without over-intervention
Winter on the Mediterranean coast is not a period of total dormancy, but it is one of slow growth. It is a good time to review the garden's structure: climbing supports, stakes, edging and irrigation systems. It is also a time to plan plantings and transplants of specimens to be moved before spring. However, indiscriminate hard pruning should be avoided: in many Mediterranean species, hard winter pruning stimulates early growth that may coincide with occasional frosts.
Another common mistake is to switch irrigation off completely for weeks. In dry, windy winters, newly planted specimens and pots can dehydrate without this being obvious at a glance. Checking moisture at depth, not just at the surface, allows you to decide whether a specific watering is needed. Gardening in Sotogrande demands this attention to detail because the difference between a wet winter and a dry one completely changes the requirements.
- Use winter to check and repair the irrigation network before spring.
- Do not turn irrigation off entirely; check moisture in pots and recent plantings.
Spring: the time to decide in advance
Spring concentrates most of the tasks, which is why they should have been planned in winter. It is the time to plant aromatic herbs, shrubs and trees, to review mulching and to adjust irrigation gradually. In Marbella and Estepona, spring can arrive with early heat; planting in April without planning for May irrigation is a mistake that is paid for in summer. The decision of what to plant and where must consider exposure and space for adult roots, not only the size of the plant at the nursery.
Staggered flowering requires choice, not improvisation. Mixing early- and late-flowering species maintains colour without depending on excessive watering. It is also the moment to review mulching: a layer of organic material reduces evaporation and protects the soil, but it must be kept away from the crown of the plant to avoid rot.
- Plant in spring only if you can guarantee irrigation through the first summer.
- Renew the mulch before the heat arrives, leaving the crown of the plants free.
Summer: efficiency and daily observation
Summer is the season that most conditions the Mediterranean garden. The main task is not to water more, but to water better: check the uniformity of sprinklers and drippers, adjust schedules to cooler hours and verify that water reaches every plant. A frequent mistake is to increase irrigation duration without checking whether the water penetrates or is lost as runoff. In clay soils, short repeated waterings may moisten only the surface.
Pruning and planting should also be moderated in high summer. Structural work, clearing dry leaves and checking shade can be done, but transplanting and heavy fertilising should wait. Observing the garden early in the morning allows signs of water stress to be detected before they become serious: rolled leaves, loss of gloss or wilting of young shoots are signals to review irrigation, not to add more water without judgement.
- Check irrigation uniformity by placing containers at different points and measuring what they collect.
- Avoid transplanting in high summer; if unavoidable, provide shade and supplementary watering.
Planning mistakes worth avoiding
One of the most common mistakes is copying the calendar of another climate or another locality without adapting it to the specific exposure and soil. A west-facing garden in Estepona does not behave like one shaded by trees in Sotogrande. Another mistake is to pile up tasks in spring and abandon the garden in autumn, when drainage problems are precisely corrected and the soil is prepared. Useful seasonal planning is the kind that reserves time to observe and correct, not only to execute.
Finally, avoid the temptation to do everything at once: pruning, fertilising and planting in the same week leaves the garden with no capacity to respond if something goes wrong. Spacing tasks out and noting results allows you to learn from the garden itself and adjust the following season's decisions with real information.
- Divide tasks by zones and by weeks; do not concentrate everything into a single weekend.
- Record what worked and what did not after each season to adjust next year's calendar.
